Binance Spot WebSocket Skill

Security checks for vulnerabilities and agentic risk

Overview

This skill is a focused guide for subscribing to public Binance Spot market streams and does not show hidden credential use, private account access, or destructive behavior.

Before installing, confirm you are comfortable with public market data being written to local NDJSON files under your home directory and remember to stop subscriptions when finished so they do not keep consuming network and disk resources.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Finding

This code chunk does not implement the declared skill behavior of subscribing to Binance Spot public market streams. Instead, it validates that associated files exist and contain required text patterns such as the Binance endpoint, websocket transport guidance, and example stream names. While these checks support the packaging/documentation of such a skill, the actual behavior of the code shown is materially different from the declared purpose. Therefore this chunk is a mismatch.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

The usage examples repeatedly direct WebSocket stream output into files under $HOME/.uxc/subscriptions/, which creates persistent local data, but the markdown does not warn users that running these commands will write files to disk. Under the markdown-file criteria, behaviors that affect user data or system state should be disclosed.
